Aaron Putnam sits stop a boulder high in the Sierras of central California, banging away with hammer and chisel to chip out a sample of ice age history. Each hunk of rock is a piece of a vast puzzle: How did our climate system ...

For the 100 million people who live within 3 feet of sea level in East and Southeast Asia, the news that sea level in their region fluctuated wildly more than 6,000 years ago is important, according to research published ...

Less than a year after the first research flight kicked off NASA's Oceans Melting Greenland campaign, data from the new program are providing a dramatic increase in knowledge of how Greenland's ice sheet is melting from below. ...

Ocean rise already is worsening the floods and high tides sweeping California this stormy winter, climate experts say, and this month's damage and deaths highlight that even a state known as a global leader in fighting climate ...

Coastal ecosystems and aquifers will be greatly affected by climate change, not only from rising temperatures and more volatile weather, including changes in precipitation patterns, but also from sea level rise.

In the last days of Barack Obama's administration, US government scientists warned even more sea level rise is expected by century's end than previously estimated, due to rapid ice sheet melting at the poles.

If you've visited the Outer Banks or other barrier islands, you've likely experienced their split personalities—places where high waves can pound the sandy ocean shore while herons stalk placid saltmarsh waters just a short ...
